ERNEST E. GAMON, OF NEWARK, NEW JERSEY.

WATER-METER.

To all whom it may concern:

Be it known that I, ERNEST E. GAMON, a citizen of the United States, residing in the city of Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in IVate-r- Meters, of which the following is,a full, clear, and exact description, such as will enable others skilled in the art to which it pertains to make and use the same.

My invention relates to water meters of the disk type, comprising an outer inclosing case and an inner piston chamber in axial alinement with the inclosing case and circumferentially free therefrom, the disk chamber being provided with suitable inlet and outlet ports and containing the nutating piston or disk.

The inlet and outlet ports of the disk chamber communicate with inlet and outlet ports or spuds in the outer inclosing case, the spuds being connected to the water pipes in the usual way.

The object of my invention is to simplify and cheapen the construction by attaching the disk chamber in a simple manner to an annular boss in the bottom of the inclosing case, and having the outlet port of the disk chamber communicating through the annular boss with the outlet spud. It will be seen that this construction permits a free circulation of the water about the disk chamber thus equalizing the pressure and breaking up the current before it enters the disk chamber. Furthermore, the simple screwattachment reduces the amount of machining and fitting necessary and facilitates assembling the parts.

In carrying out my invent-ion, I make use of the construction illustrated in the acconr panying drawings, in which Figure 1 shows a vertical elevation, the lower part being broken away and shown in section. Fig. 2 is a plan view; and Fig. 3 shows a modification.

Similar letters of reference refer to like parts throughout the specification and drawings.

The inclosing case is composed of two shell-like castings A and B fastened together in any suitable manner as by bolts 0. The upper casting A has the register inclosing compartment D cast on or otherwise secured Serial No. 496,852.

provided with the usual with the tubular channel F extending downward as a rib on the exterior of the inclosing case B and opening into the interior of the inclosing case B near the bottom thereof, as shown in Fig. 1.

An annular boss H rises from the bottom of the casting B and is in direct communication with the outlet spud G through the tubular channel G which extends rib-like along the exterior of the case B, diametrically opposite the inlet tube F, as clearly shown in Fig. 1. The boss H is internally threaded at I and surfaced off to form the seat K upon which the disk chamber L, L is secured by the depending stem M which is provided with the tubular threaded boss N, taking into the threads I of the boss H. The under face of the stem M is surfaced off to coact with the seat K to form a water tight joint.

In a water meter, the water is usually caused to flow through the disk-chamber in a counter-clockwise direction, in which case, the threads I may be made left-handed so that the frictional act-ion of the flowing water in the disk chamber will tend to maintain a tight oint at K, although I have used a right-hand thread with satisfactory results.

It will be seen that the disk chamber L, L is spaced away from the inclosing case A, B, thereby forming a receiving chamber for the inflowing water from the spud F. The disk chamber is made up of two sections L and L, secured together in any suitable manner, as by screws L and provided with inlet and outlet ports. The inlet port is similar to that in common use in meters of this type, and opens directly into the receiving chamber above mentioned, While the outlet port opens into a pocket R cast integral with the sections of the disk chamber and is continuous and integral with a tubular cavity S cored in the stem M, depending from and in- Patented June 14, 1910.

tegral with the lower section L of the disk chamber. A supplemental port R is added to give more free egress of the water from the disk chamber to the channel S. The outlet port of the disk chamber is thus connected to the outlet spud Gr by a sinuous tubular channel which leads through the central boss li.

It will be seen that in manufacturing, all the fitting necessary will be at the seat K, and this can be quickly and cheaply done by facing off the upper face of the annular boss H and the lower face of the stem M and cut ting the threads.

hear the bottom of the lower section B of the inclosing case, is placed strainer T of perforated metal. It is made annular in shape to fit over the boss H and may be held in place in any desired manner, as by the overhanging edge of the depending disk chamber stem M. The cavity thus formed below the strainer T serves as a receptacle for gravel and other particles separated from the inflowing water by the strainer T.

The disk chamber is provided with the usual nutating piston U having a ball bearing V and gear train actuating rod W, which being of usual construction, require no special description here.

In carrying out my invention, the disk chamber may be attached to the bottom of the inclosing case in various ways. In Fig. 3 is shown a modification in which a larger annular boss H is employed to support the disk chamber L which is provided wit-h a corresponding depending annular boss M". The surfaces of the bosses H and M are faced off to form the water tight seat at K An additional central boss H is provided and internally threaded to receive a central lug or bolt M depending from the under side of the disk chamber L The outlet port of the disk chamber communicates by an integral pocket R with the annular cavity S, the latter communicating with the outlet spud G which is cast with the inclosing case B The inlet spud F communicates with the receiving chamber formed between the disk chamber and the outer inclosing case, as in the previously described construction.

The operation of my improved meter should be sufiiciently clear from the description and an inspection of the drawings.

The flow of the water may be traced by following the arrows from the inlet spud F through the tubular channel F and up through the strainer T to the receiving chamber about the disk chamber L, L, then through the disk chamber and out through the ports R, R down through the channel S and the boss H up through the tubular channel G and out through the spud G.
